this material entersbetween. the frames, and thus causes upon the=closing of the frames, in-

jury to the hinges, and at the same time a V vwearing of the bag material results. I

The invention consists in the provision of a hinge axisin line with the meeting edgesof the. two parts of the frame,whereby the bag mate- I vertical part orleg, Bfor.C',has a projection with, alug 23, and this lug engagesan' opening rial is kept below the hinge line, and in the pro.-

ision of'ears struck out of the material of the frames,the axis of the hinge being also in line with that line coincident with the contacting surface of the two-partsof the frame when in closed position, the flange of the ears being at rig'htangles to the plane ofthe adjacent surfaces when the frame is closed. .Another feature of the inventiongcontemplates animproved form ofrfastening the parts ofthe frame to- 7 gether, so as to assure proper hinge action.
